こんばんは！ Taking a few mock tests for JLPT4, I found that many (TRICKY!) questions concern what verb mode precedes a given word / construction. So, I arranged all the various (basic) grammar expressions I have studied so far, sorting them by the verb mode they use. I hope other beginners like me find this useful.
Thanks well in advance to coco, harisenbon, and all the other pros that I'm sure will be so kind and correct any mistakes and/or fill in any missing pieces. Just keep in mind this is intended for beginners and low intermediates ください.

"−>" is how you construct the mode from the dictionary form.
"−−＞" means "verb mode followed by".
